British police have arrested a suspect wanted in Spain in connection with last year's March 11 train bombings in Madrid in which nearly 200 people died.

Police identified the man as 39-year-old Spaniard Moutaz Almallah Dabas. They said they were acting on an extradition warrant from Spain when they took him into custody at Slough, west of London. Mr. Almallah Dabas is wanted for alleged terrorist offenses linked to the Madrid train bombings.

He is due to appear in London's Bow Street magistrate's court on Monday.

On Friday, Spanish police arrested his brother, Mohannad Almallah Dabas, who holds a Syrian passport, also in connection with the Madrid train bombings.
